Abstract: An embodiment method for grant-free resource configuration comprises configuring a first type of grant-free resource, wherein the first type of grant-free resource is cell-specific and is configured using broadcast signaling, and wherein the first type of grant-free resource is accessible to a UE without further configuration; and configuring a second type of grant-free resource, wherein the second type of grant-free resource is UE-specific and is configured using a combination of broadcast signaling and unicast/multicast signaling, and wherein the second type of grant-free resource is accessible to a UE only after the unicast/multicast configuration.

Abstract: Methods are disclosed that enable a user equipment (UE) to receive cell specific, UE specific and, in some embodiments, Physical Uplink Shared Channel (PUSCH) specific parameters from a network side component, such as a transmit/receive point, and use that information to set at least one PUSCH transmit power when transmitting to the network side.

Abstract: A method for uplink transmission by a UE includes obtaining information regarding a plurality of power control sets each having a plurality of power control parameters, wherein a value of at least one parameter in a first power control set is different from a value of the at least one parameter in a second power control set; obtaining information associating at least one of the power control sets with at least one operational property of the UE; and when at least one of the operational properties is in effect on the UE, transmitting a PUSCH using the parameters of the power control set associated with the at least one operational property in effect.

Abstract: A user equipment (UE) may determine that a transmission resource includes a first orthogonal frequency-division multiplexing (OFDM) symbol that is configured as a downlink symbol or as flexible, where the transmission resource is allocated for uplink (UL) transmissions during a time duration, and includes K transmission occasions (TOs). The UE may transmit a first UL transmission in the transmission resource omitting the first OFDM symbol. The first UL transmission includes K repetitions to be transmitted in the respective K TOs, and the K repetitions includes an initial transmission and at least one retransmission of the initial transmission.

Abstract: A method for determining synchronization of uplink timing in a machine type communication (MTC) system comprising a machine type communication device (MTCD) and a network element is disclosed that takes advantage of the MTCD being at a fixed location relative to the network element. The method includes receiving at the MTCD an uplink timing adjustment value from the network element and storing the uplink timing adjustment value at the MTCD. The MTCD then uses the stored uplink timing adjustment value from a previous uplink transmission for synchronizing uplink timing for a subsequent uplink transmission from the MTCD to the network element even following a period of inactivity of the MTCD, or expiration of any existing maximum uplink timing alignment period permitted for use of the timing adjustment value by the MTCD, or MTCD clock drift.

Abstract: A method and apparatus to configure grant-free transmission resources are provided. At least two configuration options can co-exist for configuring the grant-free transmission resources. The base station may explicitly or implicitly notify a user equipment which option is selected for grant-free transmission by that user equipment.
